#include using namespace std;

int main () { cin >> *new int () >> *new int (); cout << *(new int () - 16) + *(new int () - 16) + 1; return 0; }

#include<bits/stdc++.h>
using namespace std;

int main(){
    int a,b;
    cout<<a+b;
    return 0;
}

废话不多说，定义两个变量直接输出它们的和即可，别整那些没用的。

//位运算
#include <bits/stdc++.h>
using namespace std;
int add(int a, int b) {
    if (b == 0) return a;
    return add(a ^ b, (a & b) << 1);
}
int main() {
    int a, b; scanf("%d%d", &a, &b);
    printf("%d\n", add(a, b));
    return 0;
}

//暴力
#include <bits/stdc++.h>
using namespace std;
int main() {
    int a, b; scanf("%d%d", &a, &b);
    for (int i = min(2 * a, 2 * b);i <= max(2 * a, 2 * b); i++)
        if (a + b == i) {
            printf("%d", i); 
            return 0;
        }
}

//能过的
#include <bits/stdc++.h>
#define ___ int
#define $$$ main
#define _$_$_ return
#define _ cin
#define $ cout
#define __ using
#define $$ namespace
#define o_o std
__ $$ o_o;
___ $$$(){
    ___ _$o$_,$o_o$;
    _ >> _$o$_ >> $o_o$;
    $ << _$o$_ + $o_o$;
    _$_$_ 0;
}

//不用变量
#include <iostream>
using namespace std;

int main ()
{
    cin >> *new int () >> *new int ();
    cout << *(new int () - 16) + *(new int () - 16);
    return 0;
}

没啥可说的，上代码 #include using namespace std; int main() { int a,b; cin>>a>>b; cout<<a+b; return 0; }
